Rivian repurposes EV batteries for energy storage at production plant to cut costs and grid strain

These batteries will provide energy during periods of peak demand, which can also help reduce the load placed on the energy grid.

Adding built-in power capacity to its production plant lets it charge these batteries when rates are lowest and use their stored power when costs peak, reducing production costs.

The idea is that less capacity would be needed from the electric grid if companies used more systems like this to level out peak demand and meet their ever-increasing electricity appetites.
